S2J General Purpose Rectifier Diode 600V 2A DO-214AA Equivalent & Substitute Parts

Part Overview

The S2J is a general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600V DC reverse voltage and 2A average rectified current in a DO-214AA (SMB) surface mount package. This component is classified as Active product status and is RoHS3 compliant. Alternative part numbers are necessary to address packaging format requirements, automotive qualification needs, or inventory availability across different suppliers and distribution channels.

Substitute Part Grouping Explanation

Substitution of the S2J rectifier diode is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain 600V DC reverse voltage (Vr) maximum to ensure circuit protection and reliability.

Current Rating: The 2A average rectified current (Io) is the primary load-carrying specification. Substitutes with equal or higher current ratings (2A or greater) are electrically compatible. Parts with lower current ratings (1A or 1.5A) are not suitable for direct substitution.

Package Type: The DO-214AA (SMB) surface mount package is the mechanical standard. Substitutes must use identical or compatible package designations to ensure PCB footprint compatibility.

Recovery Characteristics: Standard recovery (>500ns) and fast recovery (≤500ns) diodes are both acceptable, as recovery speed does not prevent functional substitution in general purpose rectification applications.

Packaging Format: Cut Tape (CT) and Tape & Reel (TR) formats are interchangeable for component procurement; the difference is in supply and handling, not electrical performance.

Compliance & Qualification: RoHS3 compliance is maintained across all listed substitutes. Automotive-qualified variants (AEC-Q101) are available but not required for non-automotive applications.

Engineering Selection Recommendations

Direct Equivalent (Identical Electrical & Mechanical Specifications):

S2JH is the direct equivalent to S2J, differing only in packaging format (Tape & Reel versus Cut Tape). Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical characteristics, temperature range, and RoHS3 compliance. Selection between S2J and S2JH depends on procurement and assembly requirements.

Full Current Rating Substitutes (600V, 2A, DO-214AA SMB):

MURS160-E3/52T, MURS160-E3/5BT, MURS260-E3/52T, and MURS260-E3/5BT all maintain the 600V voltage rating and 2A current capacity in the DO-214AA SMB package. These Vishay parts feature fast recovery characteristics (≤500ns) compared to the S2J standard recovery (>500ns). All are RoHS3 compliant and Active product status. The MURS260 series exhibits higher forward voltage (1.45V @ 2A) compared to S2J (1.15V @ 2A), resulting in increased power dissipation. The MURS160 series specifies forward voltage at 1A rather than 2A, requiring application-specific thermal analysis.

Reduced Current Rating Substitutes (600V, 1.5A, DO-214AA SMB):

MURS360S-E3/52T and MURS360S-E3/5BT are rated for 1.5A average rectified current. These parts are suitable only for applications where the circuit load does not exceed 1.5A. Both are Vishay products with fast recovery characteristics, RoHS3 compliance, and extended temperature range (-65°C to 175°C).

RS2J-13-F is a Diodes Incorporated part rated for 1.5A in DO-214AA SMB package with Cut Tape packaging. This part is suitable for 1.5A maximum load applications.

Lower Current Rating Substitutes (Not Recommended for Direct Substitution):

MURS160-13-F is rated for 1A average rectified current and is not suitable for direct substitution in circuits designed for 2A operation.

Package Variant (Different Mechanical Form Factor):

RS2JA-13-F is a 1.5A rated diode in DO-214AC (SMA) package, which has different PCB footprint dimensions than the DO-214AA (SMB) package. This part requires PCB redesign and is not a direct mechanical substitute.

Automotive Qualification:

S2JH includes AEC-Q101 automotive qualification, making it suitable for automotive applications where S2J may not be approved.

Frequently Asked Questions (FAQ)

Q: Can MURS160-13-F replace S2J in my circuit?

A: No. MURS160-13-F is rated for 1A average rectified current, while S2J is rated for 2A. Using a 1A-rated diode in a 2A circuit will cause the component to exceed its current rating, resulting in excessive heat generation and potential failure.

Q: What is the difference between S2J and S2JH?

A: S2J and S2JH are electrically identical. The difference is packaging format: S2J is supplied in Cut Tape (CT) format, while S2JH is supplied in Tape & Reel (TR) format. Both have identical electrical specifications, temperature range, and compliance status. Selection depends on assembly line requirements and inventory management.

Q: Can I use MURS260-E3/5BT instead of S2J?

A: Yes, electrically. MURS260-E3/5BT maintains 600V voltage rating and 2A current capacity in the same DO-214AA SMB package. However, forward voltage is higher (1.45V @ 2A versus 1.15V @ 2A), resulting in approximately 0.3V additional voltage drop and increased power dissipation. Thermal design must account for this difference. MURS260-E3/5BT also features fast recovery (75ns) versus S2J standard recovery (1.5µs).

Q: Why would I choose a fast recovery diode over standard recovery?

A: Fast recovery diodes (≤500ns) reduce switching losses and electromagnetic interference in high-frequency applications. Standard recovery diodes (>500ns) are suitable for line-frequency rectification and general purpose applications where switching speed is not critical.

Q: Is RS2JA-13-F compatible with my S2J circuit?

A: RS2JA-13-F has different mechanical packaging (DO-214AC SMA versus DO-214AA SMB) and lower current rating (1.5A versus 2A). This part requires PCB footprint redesign and is suitable only for circuits with maximum 1.5A load. It is not a direct substitute.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed in this document are RoHS3 compliant and maintain compliance with REACH regulations. All parts are classified as Active product status.

Q: What is the temperature range difference between S2J and substitute parts?

A: S2J operates from -55°C to 150°C junction temperature. Most Vishay substitutes (MURS series) extend the upper limit to 175°C. Diodes Incorporated parts (MURS160-13-F, RS2J-13-F) extend to 175°C or maintain 150°C depending on the specific part number. Extended temperature range provides design margin for high-ambient or high-power applications.

Q: Can I use MURS360S parts as a substitute?

A: MURS360S parts are rated for 1.5A, which is below the 2A rating of S2J. These parts are suitable only for applications with maximum 1.5A load requirement. They are not suitable for direct substitution in 2A-rated circuits.

Q: What does "Cut Tape" versus "Tape & Reel" mean for component selection?

A: Cut Tape (CT) and Tape & Reel (TR) refer to supply formats, not electrical performance. Cut Tape is supplied in smaller quantities on tape that is cut to length. Tape & Reel is supplied on continuous reel for automated assembly. Both formats contain identical components; selection depends on assembly equipment and order quantity requirements.
